CASE STUDY
The first mammal to be cloned from a somatic (body) cell of an adult was Dolly the sheep. She was made in 1996 at the Roslin Institute in Scotland, using a technique called somatic cell nuclear transfer. In this technique, the nucleus of a cell from a donor's body is combined with an enucleated egg (one with its nucleus removed) from a female of the same species, and the resulting cell is stimulated to start dividing and grow into an embryo. The embryo is then placed in the uterus of a surrogate mother to continue its development. Although additional sheep, as well as pigs, cattle, goats, horses, rabbits, and mice, have been cloned using somatic cell nuclear transfer, one problem with this method is the low survival rate. Most embryos do not survive long enough to be implanted in a surrogate mother. And of those that do, almost one-quarter of the clones born have health problems so severe that they do not reach adulthood.
